Detailed Description

Example 1

As shown in fig. 1 to 4, a combination gearshift device includes a first shaft 1, a second shaft 2 and a handle 4, the first shaft 1 and the second shaft 2 are alternately arranged and are mounted in a housing 3 through bearings, and preferably, they are arranged perpendicular to each other, thus facilitating the operation. As shown in fig. 1, the second shaft 2 is located above the first shaft 1, and preferably, the second shaft 2 is in a shape of a convex crank shaft, as shown in fig. 4, that is, the second shaft 2 is low at two ends and high in the middle, so that the second shaft 2 can not interfere with the first shaft 1, and the space can be saved, an axial groove 22 is arranged on the protruding part of the second shaft 2, and the handle 4 passes through the axial groove 22 and is hinged with the first shaft 1 through the small shaft 12. As shown in fig. 2, the handle 4 can swing left and right to drive the second shaft 2 to rotate relative to the housing 3, and the handle 4 can also move up and down in the axial groove 22 to drive the first shaft 1 to rotate relative to the housing 3.

The first shaft 1 is provided with a first connecting rod 11 on the shaft between the shell 3 and the handle 4, the first connecting rod 11 is hinged with a first pull rod 5, the first pull rod 5 is connected with a reversing rod of the gearbox, so that the reversing rod of the gearbox can be controlled to change speed, the reversing rod of the gearbox can be controlled to reverse, and a vehicle can move forward or backward.

As shown in fig. 2, the second connecting rod 21 is arranged on the shaft of the second shaft 2 between the housing 3 and the handle 4, the second connecting rod 21 and the first connecting rod 11 are positioned on the same side of the second shaft 2 and are respectively arranged at two ends of the second shaft 2, so that the space of the housing 3 can be fully utilized, the second connecting rod 21 is connected with a gear lever of the gearbox through the second pull rod 6, the speed of the vehicle can be increased from 1-gear to 4-gear, the speed of the vehicle can be reduced from 4-gear to 1-gear, preferably, the second pull rod 6 is a flexible shaft, so that the space can be saved, the interference can be avoided, and the installation and the maintenance are convenient.

The working principle of the utility model is as follows, the front handle 4 is operated to be positioned at the neutral position, namely the position of figure 2, when the vehicle is required to go forward or go backward, the handle 4 is pushed to move upwards (as shown in figure 2, the same is applied below) to drive the first shaft 1 to rotate upwards, the reversing control lever of the gearbox is pressed downwards through the first connecting rod 11 and the first pull rod 5, and the vehicle is shifted from the neutral position to the forward position, so that the vehicle goes forward; the push handle 4 moves downwards to drive the first shaft 1 to rotate downwards, the reversing operating lever of the gearbox is pulled upwards through the first connecting rod 11 and the first pull rod 5, and the vehicle shifts from a forward gear to a neutral gear position to stop the vehicle; the handle 4 is continuously pushed to move downwards to drive the first shaft 1 to rotate downwards, the reversing operating lever of the gearbox is pulled upwards through the first connecting rod 11 and the first pull rod 5, the vehicle is shifted from a neutral position to a backward shift position, and the vehicle is backward; the pushing handle 4 moves upwards to drive the first shaft 1 to rotate upwards, the reversing operating lever of the gearbox is pressed downwards through the first connecting rod 11 and the first pull rod 5, the vehicle is replaced from a backward gear to a neutral gear, and the vehicle is stopped, so that the forward, stop, backward and stop actions of the vehicle are realized.

When the pushing handle 4 moves leftwards to drive the second shaft 2 to rotate leftwards, the second connecting rod 21 of the second shaft 2 drives the second pull rod 6 to pull the gear shift operating lever of the gearbox upwards, so that the speed of the vehicle is changed from the 1-gear speed to the 2-gear speed, the pushing handle 4 is continuously pushed leftwards, and the speed of the vehicle can be gradually changed from the 1-gear speed to the 4-gear speed at one time.
